[extension/opamp] Implement ReportsHealth capability

Describe the issue you're reporting

The documentation states that opamp extension should support 3 capabilities:

The opamp extension implements an OpAMP client with a small subset of OpAMP agent capabilities:

• ReportsStatus
• ReportsEffectiveConfig
• ReportsHealth. The extension reports Collector's health on startup and any time the health changes. In order to do this the opamp extension needs access to the health of the Collector. [...]

In opamp extention source code, ReportsHealth is not currently implemented. Unless left out deliberately, please consider prioritizing it so that opamp extension would support all 3 basic capabilities.
